14 Claims. (Ci. 20645.19)

Thisinvention relates to paperboard cartons, and it has particularreference to a carton for use in the packaging of incandescent lamps insuch a manner as initially to afford an assembly of the lamps with theflat-folded carton which will present their bases in position fortesting purposes, and ultimately, as after such testing, and squaring-upor erecting of the carton from its flat-folded condition, to enclose thelamps for handling, shipment, storage, display and sale.

One of the objects of the invention is to provide a carton which willfurnish a display package for miniature incandescent lamps of the typeused as Christmas lights so that such lamps may be available for shelfdisplay in packages of appropriate multiples; and in order that noimperfect lamps will be included in the packages the carton is so formedthat after the lamps are assembled with it their bases will project inposition for testing prior to completion of the packaging operationwhereby substitutions of lamps may be made where necessary or thepartially completed package of the multiple of lamps discarded, at leasttemporarily, from the production line.

Another object of the invention is to provide a carton of the typereferred to which is erectable from flat-folded to squared-up conditionwhile the lamps are assembled with it, and which, after such erection,will enclose the lamps in proper relation, and in injury-resistantretention, for handling, shipment, storage, display and sale.

A further object is to provide a carton of this type in which one of itswall panels is furnished with a window opening through which theassembled, packaged lamps will be displayed.

Another object is to provide a carton of this type which is formed froma single, integral blank of paperboard material which may be folded toflat form, with chosen parts adhesively secured, by simple andinexpensive procedures of well recognized efiiciency.

With these-and other objects in view, as will appear hereinafter, theinvention is directed to a carton which, in the interest of simplicity,economy, ease of handling and functional adequacy, is preferably in theform of an openended tube comprising a single, integral blank ofpaperboard material provided with cuts and folding scores to definetherein a front wall panel, a rear wall panel and top and bottom edgewall panels, such blank being fiatfolded upon two of its folding scoresand adhesively secured in tube form so that portions of at least two ofits wall panels are in juxtaposition, substantially registering lampbase receiving apertures in such juxtaposed portions in which the lampsto be packaged are accommodated in projection through the fiat-foldedblank for testing purposes, a window opening in said front wall panelthrough which the lamps are displayed in the ultimately erected carton,and preferably means adjacent to such window opening for engagement withthe base-opposite tips of the lamps to hold them erect within the set-upcarton; the carton, with the lamps assembled therewith in. itsfiat-folded condition, being erectable to set-up package form by asimple manipulation of the carton parts, all as will be explainedhereinafter more particularly and finally claimed.

As will be apparent particularly from the showing of It will be noted,moreover, that the cartons of individual blanks are, as shown, designedfor the packaging of five lamps, which is in accordance with a preferredmerchandising practice.

Furthermore, especially in the case of miniature lamps of the smallersizes, it may be desired to present them for sale in multiples of ten atthe option of the purchaser, and to this end the cartons may befurnished as split cartons each of which comprises two of the individualfive-lamp cartons joined along, and optionally capable of beingseparated, or split, upon an intervening cut score line, as indicated bythe showing of Figs. 9 to 11.

Obviously, also, the cartons may be designed for the packaging of lampsin multiples of other than five lamps, or for the packaging ofindividual lamps, and by the split carton arrangement packages ofvarious desired multiples of lamps may be presented for sale as unitpackages.

The blank of the carton of Figs. 1 to 8 shown particularly in Figs. 1 to3 as being one of a longitudinal plurality or multiple thereof separatedfrom its longitudinally adjacent similar blanks by spaced cut-scores 1,comprises, seriatim, a top edge wall panel 2, a front wall panel 3, abottom edge wall panel 4, a rear wall panel 5, and a glue flap 6, theseelements of the blank being defined by its free edges 8 and 9 and,intermediately, by folding scores 10, 11, 12 and 13.

The front wall panel 3 is provided adjacent to its ends with similarcuts 14, preferably of arcuate shape for a purpose hereinafterexplained, to provide a window opening, and the material of the blankwithin the window opening is cut longitudinally, as indicated at 15 toform therefrom a lamp supporting shelf member 16 hinged upon a foldingscore 17 and a retaining flap 18 hinged upon the folding score betweenthe top edge wall panel 2 and the front wall panel 3.

The shelf member 16 is provided with a longitudinal series of apertures19 of a size to receive and preferably frictionally engage thethrough-projected bases of the lamps to be packaged, and theaperturesare so relatively spaced as to hold the packaged lamp out of possiblecontact with each other.

The retaining flap 18 is provided with notches 20 equal in number to andaxially aligned with the apertures 19 of the shelf member and serving,in the completed package, to engage and properly position the tips ofthe packaged lamps. Those portions of the cut which extend across thenotches of the retaining flap 18 are offset from the balance of the cut15 to furnish upon the free edge of the shelf member off-standing lugs21 for engagement with the rear wall panel 5 when the carton is in itserected, square-up condition.

The rear wall panel 5 is provided with a plurality of apertures 22 solocated that when the carton blank is fiat-folded to tube form, Figs. 2and 3, with the top edge wall panel adhesively joined to the glue flap6, they will substantially register with the apertures 19 of the shelfmember 16 of the front wall panel 3, Fig. 3.

Considering the blank of Fig. 1 to be shown as presenting its innerface, the folding and securing of it in tube form, as viewedparticularly in Fig. 3, is accomplished by folding the rear wall panel5, with its attached glue flap 6, upwardly upon the folding score 12 andthen downwardly so that it lies flat over the bottom edge wall panel 4and a portion of the front wall panel 3. Then, with glue applied to theglueflap 6, preferably prior to its folding with the rear wall panel 5,the top edge wall panel 2 is folded over upon it on the folding score 10and adhesively afiixed to it by the applied glue.

As shown in Fig. 4, a plurality of the lamps L to be packaged may havetheir bases L' inserted through, and frictionally gripped in, theapertures 19 of the shelf member 16, and, inasmuch as these lamps arethus assembled while thecarton is in flat-folded condition, their baseswill extend through the mating, substantially registering apertures 22in the rear wall panel 5, and will project below such panel sufficientlyto permit their engagement with, or by, testing apparatus, so that,while the carton is flatfolded, any defective lamps may be detected andreplaced with perfect ones.

After appropriate testing of the lamps the carton will be squared up toits fully erected condition by application of pressure at the edge foldsof the folding scores 10 and 12, bending inwardly and downwardly of theshelf member 16 and bending inwardly of the retaining flap 18.

During the initial erecting step, by application of pressure on theopposite fold lines 10 and 12, the front wall panel 3 will be moved awayfrom the rear wall panel 5 with a parallel motion guided by the top andbottom edge wall panels 2 and 4 which form two sides of theparallelogram of the four carton wall panels, and during this motion thebases L of the lamps L, moving with the shelf member 16 will be drawnoutwardly through the apertures 22 of the rear wall panel 5. Inasmuch asthe relative movement of the front and rear wall panels 3 and 5, guidedas sides of a parallelogram by the top and bottom edge wall panels 2 and4, entails a relative displacement of the apertures 19 and 22 of thefront and rear wall panels, and as the lamps are relatively fixedlycarried by the shelf member 16 in relation substantially normal thereto,the apertures 22 of the rear wall panel are preferably made sufficientlylarge, and larger than the apertures 19 of the shelf member 16, topermit this movement of the lamp bases through them without obstruction'by, or foulingupon, their edges. This is clearly illustrated in Fig. 5.

As shown in Fig. 6, when the group of lamps L is pivoted inwardly of thesquared-up carton along with their mounting shelf member 16, their tipswill ride under the retaining flap 18 and will, when the shelf member isbent downward sufficiently, move into snap engagement with the walls ofthe notches 20 of this flap. Meanwhile, the inward and downward bendingof the shelf member 16 will bring its lugs 21 into engagement with theinner face of the rear wall panel 5, and as the dimension of the shelfmember from its hinge fold at 17 to the outer edges of its lugs 21 issubstantially equal to the inner dimension of the top and bottom edgewall panels 2 and 4 between the inner faces of the front and rear wallpanels 3 and 5, the free edges of the lugs of the shelf member willsomewhat frictionally engage the inner face of the rear wall panel tohold the shelf member in proper horizontal position and also to aid inretaining the carton in squared-up, erected condition.

if desired, the lugs 21 may be omitted from the free edge of the shelfmember 16, and this, obviously, will not impair the proper packagingcharacteristics of the carton, particularly when the diameter of thebulbs of the lamps is such that the front-to-rear dimension of the shelfmember, without lugs, will be sufiicient to span the distance betweenthe inner faces of the front and rear wall panels of the carton.

In the modified embodiment of the invention shown in Figs. 9 to 12 theblank, which may be of dual form, comprises, seriatim, a front wallpanel 23, a top edge wall panel 24, a rear wall panel 25, a bottom edgewall panel 26, an auxiliary front wall member 27, a shelf member 28, anda positioning flap 29, and these elements are rclatrvely foldable uponfolding scores 30, 31, 32, 33, 34 and 35. The front wall panel isprovided with a window openmg defined by longitudinally spaced sideborders 36, a lower border defined by an edge 37 and an upper borderdefined by the folding score 30 between the front wall panel 23 and thetop edge wall panel 24 and provided with a retaining flap 38 for thesame purpose as, and provided with notches 39 similar to, the retainingflap 18 of the form of carton illustrated in Figs. 1 to 8.

The shelf member 28 is provided with a series of lamp base receivingapertures 40, and portions of the rear wall panel and the bottom edgewall panel 26 are provided with apertures 41 which, when the blank isproperly flat-folded to tube form, will substantially register with theapertures of the shelf member 28.

Flat-folding of this form of blank to tube form is accomplished by firstfolding, as a unit, the positioning flap 2 9, shelf member 23 andauxiliary front wall member 27 upon the folding score 33 lying betweensuch auxiliary front wall member and the bottom edge wall panel, andpreferably adhesively affixing the positioning flap 29 to the underly ngPortion of the rear wall panel 25, see Fig. 10. Then the front wallpanel 23 and the top edge wall panel 24 are folded, as a unit, upon thefolding score 31 between the rear wall panel 25 and the top edge wallpanel 24, so that, as shown in Fig. 11, the free edge portion of thefront wall panel 23 will overlie, and may be adhesively afiixed to, theauxiliary front Wall member 27.

The flat folded blank of this carton, Fig. 11, may have a plurality oflamps positioned in the apertures 40 of its shelf member 28 with theirbases extending therethrough and through the underlying registeringopenings 41 formed in the juxtaposed wall portions of the carton so thatthey may be tested as hereinbefore described.

When this carton is squared-up to erected form with the complement oflamps carried by its shelf member 28, it will be apparent that, due tothe connection of the auxiliary'front wall member 27 with the front wallpanel 23, and the connection of the positioning flap 29 with the rearwall panel 25, the shelf member 28, and with it the complement of lamps,will be moved automatically to it proper packaging position to bring thelamps within the confines of the carton, and while the carton is thusbeing erected, the retaining flap 38 will be folded inwardly upon itsfolding score 30 so that as the lamps are rotated with the shelf member28 their tips may be caused to engage with the notches 39 of theretaining flap, all as indicated in Fig. 12. If desired, the positioningflap 29 need not be adhesively aflixed to the rear wall panel 25, inwhich case it can be caused to act as a frictonal positioning memberafter the carton is erected, and its parts adjusted, much in the manneras described with relation to the carton of Figs. 1 to 8.

In the modified embodiment of the invention shown in Figs. 13 to 17 therelative locations of the glue flap 42, front wall panel 43, bottom edgewall panel 44, rear wall panel 45, and top edge Wall panel 46 arealtered from the arrangementof these parts in Figs. 1 to 8 so that theapertures 47 of the rear wall panel which substantially register withthe lamp carrying apertures 48 of the shelf member 49 are located, inthe squared-up carton, adjacent to its bottom edge rather than to itstop edge. Also, portions 50 of the front wall panel which are cut fromthe retaining flap 51 to provide the desired lamp tip-engaging notchestherein are left attached to the free edge of the shelf member 49 so asto be bendable with respect thereto upon folding scores 52 forfrictional engagement with the rear wall panel 45 when the carton issquared up, as shown in Fig. 16.

The modified embodiment of the carton of the invention shown in Figs. 18to 21 is formed from a blank which embodies characteristics of the formsillustrated in Figs. 1 to 8 and Figs. 13 to 17, respectively, butdiffers from both of these forms. Although the registering openings 53areso formed in a portion of the rear wall panel 54 as to lie adjacentto the top edge wall panel 55, in much the same arrangement as that ofFigs. 1 to 8, and the shelf member 56 and retaining flap 57 are quitesimilar to those of Figs. 1 to 8, the glue flap 58 is attached to thefront wall panel 59 at its bottom edge rather than at its top edge as itis shown in Figs. 13 to 17, and is affixed to the bottom edge wall panel60.

These differences although not vital will, in some instances, makepossible production of a carton having the characteristic properties ofthe invention which is better adapted to the packaging of particulartypes of lamps, than is the carton illustrated in either Figs. 1 to 8 orin Figs. 13 to 17.

It will be apparent from the foregoing disclosure that the carton of theinvention may take a variety of forms,

particularly as regards the carton blank and its arrangement of panelelements and their mode of connection in flat-folded tubulararrangement, but in all forms provision is made for so assembling acomplement of lamps with the flat-folded blank that their bases aresuitably exposed for test purposes prior to completion of the package byerection of the flat-folded blank to squaredup, lamp enclosing,condition.

Moreover, in all of its forms the carton may be erected by a simplemanipulation of its parts while the lamps which are ultimately enclosedare carried by the shelf member, and when its erection is completed thelamps will be attractively displayed at the window opening of the frontpanel and will be supported by the shelf member and retaining flap insuch proper spaced relation as to guard them against breakage duringshipment, storage, display and handling. Also, the dimensions of thecarton, having reference to a particular type and size of lamps to bepackaged therein, are such as to reduce possible play of the lampswithin the carton to a minimum, thus further guarding against breakageand at the same time accomplishing a saving in paperboard stock andeconomy in shipping, storage and display space.

In furtherance of the saving in paperboard stock it will be noted that,informing the end borders of the window opening by arcuate cuts,provision is made for adequate display of the lamps at the ends of thepackaged rows, while at the same time reducing the overall length of thecarton and also furnishing a relatively long connecti-on between theends of these cuts and the longitudinally outstanding portions of thefront panel, and this is of particular advantage at the ends of the cutswhich join the top edge folding score of the front wall panel as ittends to avoid tearing and buckling along this folding score at theseportions, particularly during erection of the lamp-loaded, flat-foldedblank to squaredup condition. y

A further advantage of the carton of the invention is that all of itselements, including the lamp receiving and supporting shelf member, areformed from a single, integral blank, and that this blank may be foldedand glued in accordance with simple and well-known practices and bymachinery of known types.

It Will be appreciated, moreover, that the one-piece construction of thecarton is advantageous to the packager in that, after the fiat-foldedblank is loaded with its complement of lamps, it may be handled as aunit to thus provide an economy in packaging time and expense.

Various changes and modifications are considered to be within theprinciple of the invention and the scope of the following claims.
